Where can I view the Terms of Usage? You can view the Terms of Usage under the Support -> Terms of Usage link in ROAMmerchant. The Terms of Usage on this page are the same as you accepted when up logged in to ROAMpay X5 or ROAMmerchant for the first time. They are displayed in ROAMmerchant for general reference. For additional support, please refer to the Support Page in your merchant portal or contact your ISO contact.
